How did this come about? Well, Zeus concocted a plan to create an all-powerful, demi-god child with Alcmene, all without her knowledge.
Alcmene was Heracles’s real mother, but his real father – the third, divine parent – was in fact Zeus, king of the gods. His two mortal parents were the king and queen Amphitryon and Alcmene, who both raised Heracles. Technically, Heracles had three parents growing up, two who were mortal, and one who was divine.
